About Cover

The cover photo describes the ring topological structure of carbon nucleus (using vortex-fractal-ring theory), which consists from two globules with 3 protons globule substructures. As discussed by, this vortex-fractal-ring theory is a new and original view of elementary particles and the structure of atomic nuclei, atoms, and molecules. Its basics are simple for understanding through the comprehensive topological structure that does not need description by complicated mathematical formulas. This theory together with grammatical evolution can design new models of nanostructures and allows us to understand the fundamental physical and chemical reasons for the stability and reactivity of atoms and molecules.

Abstract

The nanostructured material properties are different from the bulk materials. Nanofibers are widely studied for many applications like tissue engineering, wound dressings, electronics, storage, catalysts, protective clothing, sensors, and cosmetics. In this study, pure form of one-dimensional TiO2 nanofibers have been successfully obtained by electrospinning technique and TiO2 nanopowders are synthesized by a conventional Sol-Gel method followed by high-temperature calcinations. The as-obtained products are characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy-Dispersive X-Ray (EDX) spectroscopy. The XRD results reveal the crystallite size of the synthesized material. SEM images depict the formation of nanopowders and nanofibers. EDX studies confirmed the presence of Ti and O in the prepared samples.
